Structure and operating principle of heat pump

The heat pump het pump for hot water is a type of central water heater that operates on the same principle as an air conditioner. It takes heat from the air and exchanges it into hot water through a circulation pump. Therefore, it is also called an air source heat pump. The machine operates on electricity with a capacity of 0.8 KW to heat 100 liters of hot water at 60 degrees Celsius - more efficient and safer than a conventional direct resistance electric water heater.

How heat pump works

Heat pump, also known as "central water heater", is a machine that uses the principle of thermodynamics including 4 cycles:

-Evaporation stage (the heat carrier absorbs the ambient air temperature and heats up, evaporating into a warm gaseous heat carrier, the air loses heat and condenses into water on the evaporator.

-The compressor heats up the heatsink when a compressor force is applied to it.

– Condensing stage (the heat carrier when leaving the compressor is heated up to 100 degrees Celsius and enters the condenser, where it will transfer heat to the water to heat it up to the required temperature of 55 to 65 degrees Celsius and is led to the insulation tank to keep the temperature. 

-Expansion valve (after the heat carrier transfers heat to the hot water, it continues to pass through the expansion valve to form a closed loop.

Therefore, heat pump water heaters are the optimal solution to save energy for hot water needs of families or production facilities in hot and humid climates, such as Vietnam.
